About
The character "嗵" is constructed from the mouth radical "口" combined with the phonetic component "通", which supplies its pronunciation "tōng" and links it semantically to sound, specifically functioning as an onomatopoeic element for noises such as thumping or drumbeats. It originated in vernacular Chinese without a basis in classical language, and its formation as a radical-phonetic compound has defined its role as a sound-imitating character since its introduction.
